SELF-HEATING YSOLDERINGriIRON.

Specification of Letters Patent.

Patented Dec. 24, 1907 Application filed March 2; 1905. Serial No. 248.172.

ing irons in which fuel liquid is held in a hollow handle, a burner being mounted on the handle, a bit or soldering iron being mounted so as to be heated-by the burner and a valved conductor connecting the burner with the liquid fuel supply in the handle.

The object of my invention is to providea soldering iron of the kind described wi th means for controlling the passage of the fuel liquidfrom the handle reservoir such that a constant iiow of the liquid will be obtained irrespective of the position in which the iron may be held.

In another application filed by me on January 22, 1904,11aving Serial Number 190,207,

I have described a soldering iron of my invention constructed with the above. object in view. ln that invention the reservoir or hollow handle is provided with two outlets communicating with the burner, the outlets being disposed one adjacent cach end of the handle, and two connected closures, actuated by gravity when tlie handle is tilted, bein provided for automatically and alternate y opening and closing said outlets, whereby the' lower outlet which is immersed in the fuel liquid will have its closure removed and the upper closure will be moved to close the upper outlet, thus excluding from the conductor leading from the handle to the burner the compressed air in the handle.

In the invention herein described and claimed, the reservoir handle is provided with two outlets similarly disposed, one of the outlets being always open, and a single closure actuated by gravity being employed for automatically opening and closing the other outlet when the handle is tilted to and f ro. 'lhe'employment of but a single closure simplifies the construction of the soldering iron, rendering it more certain and effective in operation, less expensive to construct, and less liable to get out of order.

My present invention provides further a 'Y y dotted line c-f of Fig. 5.

'construction in which the valved and open outlet will by gravit actuated means always be dis osed in the ower side of the handle regard ess of the rotation ofthe handle on its axis.

Other novel features are hereinafter fully described and claimed.

In the accompanying drawings illustrative ofmy invention', Figure 1 is a longitudinal central section view of one form of my invention. Fig. 2 is an enlarged longitudinal sectional view of the handle and parts con nected therewith, a portion of the shank and conductor leading to the burner being shown.

Fig. 3 is a cross sectionv taken on the dotted line c-b of Fig. 1. Fig. 4 is a cross section taken on the dotted line c-d of Fig. 2. Fig. 5 isa longitudinal central sectional view of the handle and parts connected therewith of another form of my invention, shown also in Fig. 6, and in which the positions of the two outlets do not change relative to the handle when the latter is rotated on its axis. FigQ is a view partly in elevation and partlyv in central longitudinal section of the form of my invention a part of which is shown in Fig. 5.

Similar characters of reference denote similar parts.

Referring to the 'form illustrated in the `first four figures of the drawings, 1 denotes a cylindrical tubular handle. forming the reservoir for holding the liquid fuel supply, such as gasolene. The burner comprises a perforated tube 2 mounted on the outer end of a tubular shank .3 the inner end, of whichjs secured to one end of the handle 1 byv means of acentral tubular boss 4 provided on the adjacent end of the handlel l. A supply conductor has itsinner end secured in a central hole in the end of the handle 1,' the opter end of the conductor being U shaped and the extreme end being securedto a generating 100 mounted in the vinner end of the chamber 6 105 and is adapted to close the discharge opening in the outer end of the chamber 6. The inner end of the valve stem is secured to a longitudinally 'slidable block 8 the side edges of which are screw threaded and engage the 110 sol ' vided in the casting screw threaded interior of a hand wheel 9 rotatively mounted on the rear end of the shank 3, therear end of the wheel bearing upon the boss 4 and the forward end upon a ring 10 secured upon the shank 3. The block 8 is slidabl y mounted in'oppositely disposed slots 11 provided in the walls of the shank 3. Upon the outer end of the burner tube 2 is 'mounted a bit or soldering iron 12,

lthe rear end of which is hollow and the walls of which are provided with holes 13. By rotating the wheel 9 the valve stern 7 lmay be vmoved lengthwise sov as to open or close the fully described in .the ,a oresaid application A and which permits ingress but prevents egress of the air through the tube. 15. By reciprocating the'r tube 14 airis pumped into the handle or lreservoir 1 until the proper.l

pressure is obtained. D

The swin ing frame which carries the discharge, con uctor, the ,ends of which form the two outlets of the reservoir`1 comprises the following' parts. A' longitudinal axial rod 1'6 has its rear end secured to a casting 17` which has its forward end pivotally mounted on a stud 18secured in the hole in which is secured the inner end of the conductor 5, the stud being provided with a central longitudinal hole 19 communicatin withthe. hole in the tube 5 atits outer'en and at its inner end with a passage 2O p'ro- 17. The other end of the rod 16 is slidably mounted in one end of a .tube 21 the rear end of which is secured in a transverse plate 22 mounted on a plug 23 which is. rotatively mounted at its rear end on a' central pivot pin 24 secured to a U shaped bridge 25 provided on the inner side of the central part of the rear end ofthe reservoir 1. A coil spring 26 encircles the rod 16 and bears at its forward end upon the nu`t 27 mounted onthe screw threaded o'uter end 4 of the rod, the rear-end of the spring bearing upon the forward end ofthe' tube 21.

The tension of the spring .26 retains the Y plug 23 and thecasting 17 1n engagement .With the pin 24 and the sti1d18 respectively. The casting 17 is provided with a lateral arm 28 disposed on the Vsame side and parallel with the late 22. A longitudinal conductor tube 29 as its ends secured respectively in the late 22, and the arm 28, the outer end of t e tube having a lateral hole communicatin with a' passage '20 in the casting. Slidal y mounted inthe plate 2,2and 4the arm 28 respectively is mounted a longitudinal rod 30 the outer'end of which is provided with a conical valve or closure 31 adapted to 'cover the inlet or open end, of the tube 29.

The other end of the tube 29 is always open. On the rod 30' between stop sleeves 32 veecured to the rod 3() is longitudinally 's'lidable a weight 33`adapted when the handle 1A is tilted to and fro' endwise to alternately 'strike the stop sleeves 32 and thus move the ,burner tube 2 where it is ignited and by heating the chamber 6 and outer end of the tubeor supply conductor 5 generates the oil into vapor which mixing with air taken through the lateral holes in the shank 3 and i burner tube 2 forms a combustible vapor which in burning heats the bit or soldering iron 12. When the handle 1 is tilted down ward at its forward end the weight 33 strikes the forward stop sleeve 32 and 30 forward Jthus removing the closure 31 from the outer inlet of the tube'29. Thev compressed air in the rearv upper end of the handlel 1 Will force the oil through th'e outer inlet of the tube 29, thence'through the passage 20, thence through the hole in the stud 18into the conductor 5.l If the handle 1 is ,tilted downwardly at its rear end the weight e 33 will slideon the rod 30 so as to strike the rear stop sleeve3 2 thus forcingr the rod 30 rearwardly and forcing the closure 31 into the outer inlet iend of the tube-'29,fthus preventing air in the upper-forwardend of the handle from 'passing -into the'v tube 29. In the meantime the rear end of the tube 29 being open, the oil will enter the tube from that end and passing from thence into the passage 20 enters the conductor 5. It will thus be seen that one closure is sufiicientto prevent compressed. airentering the passage 20.- In the event that the handle 1 1s rotated. on its axis the swinging frame carrying the con'- ductor 29 will swing by gravity toa position in which the' conductor or pipe 29 is in the lower-side of the handle, one end of said tube is therefore' always immersed the ,oil until the supply has become sufficiently low for replenishing,

In the form shown in Figs. 5'L 6, 7 and 8, the forward end of the instrument including the shank, burner, generator and tip or soldering iron-are constructed similari to the form hereinbefore described. In ig. 6 is forces the rod shown the exit opening of the` generating y chamber 6, saidopening being denoted by 34. 4The valve stem 7 extends rearwardl4 through the shank 3 into and through a longi-- tudinal tube 35 theends of which are secured to and extend through the two ends respec-l tivelyof the handle 1. The forward end of the stem 7 is screw threaded and fitted to a screw threaded hole provided in` the 'rear end of the chamber 6. The rear end of the stem 7 is Aprovided outside the handle 1 with a disk 36 by which the stem is rotated. -By rotating the stem 7 properly the' stein 7 may be made to 'close the exit opening-34. The rear end of the handle 1 ispr'ovided with a hole 'in which is secured an -oil inlet tube 37 the outer end of which has fitted to it a cap 38. The conductor 5 extends through the outer end of the handle 1, its rear end being closed. A 4longitudinal tube 29 which is open at both ends has its forward end secured side by side'to the rear end of the conduetor 5. 'A lateral passage39 connects the passages of the conductors 5 and 29 respectively. A longitudinally slidable rod 30 is mounted in and extends through the tube 29', the forward end being provided with the closure 31. The rear end of the rod is formed U shape, its forward arm being slidably mounted in a transverse hole provided 4in a transverse platee/t0 lsecured to the tube 35. A weight 33 is slid'ably. mounted on said arm ofthe rod 30 outside the tube 29 to the rear of the stop 32 secured on the said arm to the rear of the plate 40. l

In operating this form of my invention, the air is introduced through the tube 37 by means of an ordinary air pump such as is used for inliating bicycle tires, oil iirst having been placedV in the handle through the' i tube 37.

The cap 33 is then aixed on the tube 37. By properly rotating thestem 7 the inlet 34 may be opened permitting the oil to pass out df the chamber 6 into the burner tube 2. The handle 1 heilig vtilted downwardly at its forward end the weight will strike the stop 32 and force the rod 30 and closure 31 forward thus opening the forward end of the tube 29 and the compressed air at the rear upper end of the handle l'will force the oil into the forward end of the tube 29, thence by passage 39, conductor 5 into the generating chamber 6 where the oil is generated into vapor which passes from said chainber through the outlet 34. tilted downwardly at its yrear end, the weight 33 will slide rearwardly on the rod 30 until the weight strikes the transverse part of the U shaped portion of the rod forcing the rod and closure 31 rearwardly until the closure' -lf the handle is cient oil must always be kept in the handle to cover the tube 29 when the handle is held horizontally, otherwise air may enter the tube 29.

My invention may be modified in other ways without departing from its spirit.

Having thus described my invention, what I claim' anddesire to secure by Letters Patent, .is:-
